Description

Anlaßvorrichtung für Brennkraftmaschinen Die Erfindung bezieht sich auf eine Anlaß: vorrichtung für Brennkraftmaschinen, bei der das Ritzel auf der Anlasserwelle frei längs bewegbar und drehbar ist und über eine Freilaufkupplung mit einer Schraubenhülse verbunden ist, die auf einem Gewinde der Ankerwelle sitzt und durch einen Gabelhebel längs verschoben werden kann. Um nach dem Anlaufen der Brennkraftmaschine ein rasches Stillsetzen des Ritzels zu erreichen, ist schon vorgeschlagen worden, das Ritzel durch eine an einem feststehenden Teil des Anlassers angeordnete Bremse abzubremsen. Diese Bremseinrichtungen haben den Nachteil, daß das Ritzel auf der Anlasserwelle durch das Schraubgewinde wieder vorbewegt wird, wenn die Ankerwelle bzw. der sie antreibende Anlaßmotor langsamer zum Stillstand kommt als das Ritzel. In diesem Falle ist die Bremse schädlich, weil sie das Ritzel festhält, während die Ankerwelle noch weiterläuft. Würde das Ritzel nicht festgebremst, so würde es mit der Ankerwelle leer mitlaufen und sich nicht auf dieser verschrauben.Starting device for internal combustion engines The invention relates to on an occasion: device for internal combustion engines, in which the pinion on the The starter shaft is freely longitudinally movable and rotatable and via an overrunning clutch is connected to a screw sleeve which sits on a thread of the armature shaft and can be moved lengthways by a fork lever. After starting the Internal combustion engine to achieve a rapid shutdown of the pinion has already been proposed the pinion by a mounted on a fixed part of the starter Brake to brake. These braking devices have the disadvantage that the pinion on the starter shaft through the screw thread is advanced again when the armature shaft or the starter motor driving them comes to a standstill more slowly than the pinion. In this case the brake is detrimental because it holds the pinion while the armature shaft continues to run. If the pinion was not braked, it would run along empty with the armature shaft and do not screw onto it.

Um diesen Nachteil zu vermeiden, ist gemäß der Erfindung zwischen dem Ritzel und der Anlasserwelle eine in der Ruhelage des Ritzels wirksame Bremse vorgesehen.In order to avoid this disadvantage, is according to the invention between the pinion and the starter shaft an effective brake in the rest position of the pinion intended.

In der Zeichnung ist eine Ausführungsform der Erfindung im Schnitt dargestellt.In the drawing, an embodiment of the invention is in section shown.

a ist die Antriebswelle eines elektrischen Anlaßmotors, die bei b in dem Anlasserlagerschild c gelagert ist. Die Welle hat einen glatten Teil d und einen mit Schraubgewinde e versehenen Teil. Auf dem glatten Teil sitzt ein Ritzel f und auf dem Gewindeteil eine Schraubenhülse g. Ritzel und Hülse sind durch eine Freilaufkupplung k, die in dem Ausführungsbeispiel als Rollenfreilauf ausgebildet ist, miteinander gekuppelt. Der getriebene Teil der Kupplung und das Ritzel bestehen aus einem einzigen Stück. Das Ritzel hat einen axial in die Hülse hinein sich er=, streckenden Fortsatz i, der innen konisch ist. Die Antriebswelle a hat entsprechend einen konischen Teil h, der in den konischen Fortsatz des Ritzels paßt. Die Schraubenhülse ist etwa in der Mitte mit einer zweiteiligen Muffe m versehen, deren Teile durch einen in eine Rille der Schraubenhülse eingelassenen Sprengring n getrennt sind. Zwischen der Muffe und den Hülsenenden ist je eine Feder o und p angeordnet. In die Muffe greift ein Gabelhebel g ein, der von einem Elektromagnet r entgegen dem Druck einer Feder t bewegt werden kann, der zugleich auch den Hauptschalter des Anlaßmotors betätigt.a is the drive shaft of an electric starter motor, which at b is stored in the starter bracket c. The shaft has a smooth part d and a part provided with screw thread e. A pinion sits on the smooth part f and on the threaded part a screw sleeve g. Pinion and sleeve are through one Overrunning clutch k, which is in the Embodiment as a roller freewheel is formed, coupled together. The driven part of the clutch and the Pinions consist of a single piece. The pinion has an axially in the sleeve into itself er =, stretching extension i, which is conical on the inside. The drive shaft a accordingly has a conical part h, which is inserted into the conical extension of the pinion fits. The screw sleeve is provided with a two-part sleeve m approximately in the middle, their parts by a snap ring embedded in a groove in the screw sleeve n are separated. Between the sleeve and the sleeve ends there is a spring o and p arranged. A fork lever g engages in the sleeve, which is controlled by an electromagnet r can be moved against the pressure of a spring t, which is also the main switch of the starter motor operated.

Der Anlasser arbeitet in folgender Weise: Beim Einschalten des Elektromagnets r wird die Hülse g von dem Hebel q so weit vorgeschoben, daß das Ritzelf die durch gestrichelte Linie angedeutete Stellung einnimmt, in welcher Stellung das Ritzel ein Stück weit in den Schwungradzahnkranzs der Brennkraftmaschine eingespurt ist. Bei dieser Stellung des Hebels ist der Hauptschalter des Anlaßmotors eingeschaltet, so daß die Antriebswelle gedreht wird. Bei der Drehung der Antriebswelle schraubt sich die Hülse gegen den Zahnkranz vor und bringt das Ritzel in vollen Eingriff. Wenn nach dem Anlaufen der Brennkraftmaschi.ne der Elektromagnet r ausgeschaltet wird, wird die Hülse g von .dem Hebel zurückgeschoben. Dabei wird der Fortsatz i des ..Ritzels gegen den Konus h der Antriebswelle a. angedrückt und damit das Ritzel abgebremst.The starter works in the following way: When the electromagnet is turned on r the sleeve g is advanced by the lever q so far that the pinion eleven through The position indicated by the dashed line shows the position in which the pinion is located is meshed a little way into the flywheel ring gear of the internal combustion engine. When the lever is in this position, the main switch of the starter motor is switched on, so that the drive shaft is rotated. When rotating the drive shaft unscrews the sleeve against the ring gear and brings the pinion into full engagement. If after starting the internal combustion engine, the electromagnet r is switched off is, the sleeve g is pushed back by .dem lever. The extension i of the .. pinion against the cone h of the drive shaft a. pressed and with it the pinion braked.

Zum Abbremsen des Anlasserankers ist, wie üblich, noch eine weitere Bremse vorgesehen.As usual, there is another one to brake the starter armature Brake provided.
